Abstract:
An electronic watch or clock with an electrostatic induction generator, wherein the electrostatic induction generator has a rotary weight able to rotate with respect to a housing, a rotary member able to rotate with respect to the housing, a counter substrate fastened to the housing, a charging film arranged at one of the rotary member and counter substrate, and a counter electrode arranged facing the charging film at the other, outputs electric power generated between the charging film and the counter electrode to a quartz movement, and provides a window part at one or more locations among the dial plate, housing, or outside casing to enable rotation of the rotary member or transmission of rotation to be visually confirmed.
